IS61/64WV102416DALL IS61/64WV102416DBLL AUGUST 2019 1Mx16 HIGH-SPEED ASYNCHRONOUS CMOS STATIC RAM WITH 3.3V/1.8V SUPPLY FEATURES DESCRIPTION The ISSI IS61/64WV102416DALL/BLL are high-speed, 16M High-speed access time: 10ns, 12ns bit static RAMs organized as 1024K words by 16 bits. It is High- performance, low power CMOS process fabricated using ISSI s high-performance CMOS technology. Multiple center power and ground pins for greater noise immunity This highly reliable process coupled with innovative circuit Easy memory expansion with CS and OE design techniques, yields high-performance and low power TTL compatible inputs and outputs consumption devices. Single power supply When CS is HIGH (deselected), the device assumes a 1.65V-2.2V VDD (IS61/64WV102416DALL) standby mode at which the power dissipation can be reduced 2.4V-3.6V VDD (IS61/64WV102416DBLL) down with CMOS input levels. Easy memory expansion is Packages available : provided by using Chip Enable and Output Enable inputs. - 48 ball mini BGA (6mm x 8mm) The active LOW Write Enable (WE ) controls both writing - 48 pin TSOP (Type I) and reading of the memory. Industrial and Automotive temperature support A data byte allows Upper Byte (UB ) and Lower Byte (LB ) Lead-free available access. Data Control for upper and lower bytes The device is packaged in the JEDEC standard 48-Pin TSOP (TYPE I) and 48-pin mini BGA (6mm x 8mm).
